I have a somewhat basic question. Many transistor datasheets have something like this for the peak current:
pulse duration = 300 μs, duty cycle ≤ 1 %
What does pulse duration mean? Is it only the on time, or is it the time period (on + off time)?
so, for above, which is correct?
A) 3us on, 297us off
B) 300us on, 29.7ms off
I'm guessing B is more useful, but A might look better on paper (except if transistor is too slow). So I'm somewhat confused (not having any engineering background and all...)
